The Chargers, I think, will line up a left tackle when they face the Houston Texans to open the 2013 season. Here, following, on Cinco de Mayo weekend, are five candidates, none of whom recall a young Anthony Munoz. If the list doesn’t put you in a festive mood, bear in mind that other candidates could emerge.

1) King Dunlap. Tom Telesco signed him to a two-year deal averaging $1.85 million. With the Eagles last year, Dunlap started 11 games at left tackle. He started 20 of his 52 games played with the Eagles the last four years. Can look lost, but the long-armed Dunlap (6-foot-8, 310 pounds) is athletic and can tie up defenders. His height also can give him leverage problems. Ideally, he's a backup.

2) Max Starks. A free agent, he started three Super Bowls for the Steelers (the first with Ken Whisenhunt as offensive coordinator) and was Pittsburgh’s most durable offensive lineman last year, making all 16 starts. Because he’s younger and more consistent, I preferred him to Bryant McKinnie, the free agent who met with the Chargers this week before returning to the Ravens. As of Thursday, there’d been no movement between the Chargers and Starks, as reported by our Michael Gehlken.

3) Michael Harris. Pressed into duty by Jared Gaither’s absences, Harris started nine of his 15 games played last year despite having played only right tackle in his 42-start career at UCLA. Harris, who wasn’t drafted, had several rough outings, as to be expected, but his determination and competitiveness impressed Norv Turner and Chargers teammates. He is 24 and presumably far savvier than he was a year ago.

4) Kevin Haslam. He supplanted Harris as the starting left tackle in three of the last four games. In his first start, the victory at Pittsburgh in Week 14, Haslam held up, but in the next game, the Panthers went after him and right tackle Reggie Wells and created heavy pressure against Philip Rivers. Undrafted out of Rutgers, Haslam (6-5, 304) was cut by the Jaguars and Raiders. He missed the 2011 season with a knee injury.

5) Nick Becton. Part of Telesco’s undrafted free-agent class announced this week, Becton started 13 games at left tackle last year for Virginia Tech. As a junior, he rotated at left tackle and appeared in all 14 games. He’s a developmental candidate with left-tackle size (6-5 ¼ and 323) and good athleticism. Has small hands and needs to gain strength.
